I'm gonna continue to use this thread because I'm convinced that the bugs I'm experiencing are the same as those I reported before. I'm gonna try to sort through these piece by piece. First, I'm gonna start with FRED builds.
I'm using the 2014 MVPs with the additions of the new Leviathan, Anket, Hippocrates, Ptah, Bes and its associated cargo.
I tested all models to make sure they rendered properly and found all models work properly up to and including the March 7th build. With the 10th however, I get render issues with the Hecate, Edjo, and Skyboxes.
As you can see, engine textures on the Hecate render as transparent on the newer build, and the Edjo doesn't render at all. It'll still show the wireframe if I select it, but no maps.
Be advised, the issue with that bit of damage texture by the engines doesn't show up in FSO builds unless I disable environment mapping or spec mapping in the lab.
BTW, you can't see it, but in the builds 2018-03-10 and newer, skyboxes won't render for me in FRED or FSO.
